This study tested the phonological core deficit hypothesis among Dutch dyslexic adults and also evaluated the pattern of individual differences among dyslexics predicted by the phonological-core variable-orthographic differences (PCVOD) model (van der Leij & Morfidi, 2006) in a sample of 57 control adults and 56 dyslexic adults. It was…

The purpose of this study was to examine the simple view of reading (SVR) and contributions of verbal proficiency and reading fluency to reading comprehension for fourth-, seventh- and ninth-grade readers (N = 271). The SVR explained a significant proportion of variance in reading comprehension for all grades with decreasing explained variance in…

We present a new analysis of Whitehouse, Maybery, and Durkin's (2006, Experiment 3) data on inner speech in children with autism (CWA). Because inner speech development is thought to depend on linguistically mediated social interaction, we hypothesized that children with both autism and a nonverbal greater than verbal (NV greater than V) skills…

Full-day pre-K students from the 2001-2002 cohort were more likely to pass the 2010 7th-grade reading TAKS than were kindergarten students from the 2002-2003 cohort who were assumed eligible for pre-K but did not attend pre-K in 2001-2002. There is a full report and a separate executive summary report. [For the executive summary of this study, see…

A known-groups design was used to determine the classification accuracy of Wechsler Adult Intelligence Scale-III (WAIS-III) variables in detecting malingered neurocognitive dysfunction (MND) in traumatic brain injury (TBI). TBI patients were classified into the following groups: (a) mild TBI not-MND (n = 26), (b) mild TBI MND (n = 31), and (c)…

Background & Aims: We tested the Diagnostic and Statistical Manual of Mental Disorders (DSM) hypothesis that so-called specific developmental disorders are marked by a pattern of specific discrepant achievement, and an alternative hypothesis that children with these disorders show a pattern of relatively pervasive low achievement. Methods…

The project Adult Dyslexia and Attention Deficit Disorder in Finland (Project DyAdd) compares adults (n = 119, 18-55 years) with dyslexia, attention-deficit/hyperactivity disorder (ADHD), dyslexia together with ADHD (comorbid), and healthy controls with neuropsychological, psychophysical, and biological methods. The focus of this article is on the…

Hyperserotonemia is the most consistent serotonin-related finding in autism. The basis of this phenomenon, and its relationship to the central serotonergic dysfunction remains unclear. Platelet serotonin level (PSL) in 53 autistic adults and 45 healthy controls was measured. Mean PSL in autistic group (75.7 [plus or minus] 37.4 ng/[microliters])…

The authors compared 6- to 11-year-olds with developmental coordination disorder (DCD) and those with specific language impairment (SLI) on measures of memory (verbal and visuospatial short-term and working memory) and learning (reading and mathematics). Children with DCD with typical language skills were impaired in all four areas of memory…

Are children with an autism spectrum disorder (ASD), but normal-range intelligence, impaired on theory of mind skills measured by responses to abstract animations in the form of a computerized cartoon? Fifty-six cases and closely matched comparisons were tested. We rated verbal responses according to the length of their descriptions, their…

A longitudinal study reported positive speech and language outcomes for 29 children with hearing loss in an auditory-verbal therapy program (AVT group) (aged 2 to 6 years at start; mean PTA 79.39 dB HL) compared with a matched control group with typical hearing (TH group) at 9, 21, and 38 months after the start of the study. The current study…

Referential communication was studied in children with autism spectrum disorder (ASD) including children with autism and Asperger syndrome. The aim was to study alternative explanations for the children's communicative problems in such situations. Factors studied were theory of mind, IQ, verbal ability and memory. The main results demonstrated…

This article describes English language proficiency and bilingual verbal ability for a sample of 209 students aged 10 to 16 from three immigrant groups--Chinese, Dominican, and Haitian. Sources of data included structured student interviews, parent interviews, and individual language assessments. On average, students' English language proficiency…

The relationships among verbal skills of primary school students with learning disabilities and a typically developing comparison group were studied and compared with written tasks carried out in Estonian classrooms. Word defining, categorising/justifying, guessing, and memorising tasks were used. The participants were 251 students in Grades 2-4;…

Behavioral phenotypes of individuals with Williams syndrome and individuals with Down syndrome have been contrasted in relation to short-term memory. People with Down syndrome are stronger visuospatially and those with Williams syndrome are stronger verbally. We examined short-term memory, then explored whether dual-task processing further…
